The best way to do this is to factor both numbers.
2940 = 2 * 2 * 3 * 5 * 7 * 7
3150 = 2 * 3 * 5 * 5 * 7
Now take the ones that are common:
2 * 3 * 5 * 7. That's 210
to check, you can take the unused factors.
For 2940 that's 2 * 7 = 14 and 14 * 210 = 2940
For 3150 that's 3 * 5 = 15 and 15 * 210 = 3150
The 14 and 15 also tell us we have it right since they share no common factors.
1, 2, 3, 5, 6, 7, 9, 10 5 x 630 = 3150 10 x 315 = 3150 6 x 525 = 3150 2 x 1575= 3150 1 x 3150 = 3150 7 x 450 = 3150 9 x 350 = 3150 3 x 1050 = 3150
3150

The GCF is 420.
315 = 32 x 5 x 7525 = 3 x 5 x 73 x 5 x 7 = 105 (GCF)
The GCF is 45.
Since 315 is a factor of 3150, it is automatically the GCF.
The GCF is 42.
3150 to a percent = 315000% to put 3150 to a percent, multiply 3150 by 100%: Example: 3150 * 100% = 315000%
1, 2, 3, 5, 6, 7, 9, 10 5 x 630 = 3150 10 x 315 = 3150 6 x 525 = 3150 2 x 1575= 3150 1 x 3150 = 3150 7 x 450 = 3150 9 x 350 = 3150 3 x 1050 = 3150
9 + 2940 = 2949.
15% of 3,150 = 15% * 3150 = 0.15 * 3150 = 472.5
